Nvidia conflicts during update

I have had problems with my NVIDIA GeForce GTX 650 Ti/PCIe/SSE2 card earlier. See here.

When I tried updating my computer today with:

sudo pacman -Syyu

I got the following problem.

warning: removing 'libxnvctrl' from target list because it conflicts with 'libxnvctrl-470xx'
:: libxnvctrl-470xx and libxnvctrl are in conflict. Remove libxnvctrl? [y/N]

There were mentions of a similar problem here, here and here.

But none offered a solution.

How do I proceed so that I do not run into difficulties?

Please let me know if you need any further information.
